openKARST: A novel open-source flow simulator for karst systems
Jannes Kordilla, Marco Dentz, Juan J. Hidalgo
We introduce the open-source Python-based code openKARST for flow in karst conduit networks. Flow and transport in complex karst systems remain a challenging area of hydrogeologica…
Stochastic Modeling and Upscaling of Hydrodynamic Transport in Geological Fractures
Alessandro Lenci, Yves Méheust, Yves Méheust +2
Characterizing hydrodynamic transport in fractured rocks is essential for carbon storage and geothermal energy production. Multiscale heterogeneities lead to anomalous solute trans…
Flow induced intermittent transport shapes colloid filtration in complex media
Filippo Miele, Ankur Deep Bordoloi, Marco Dentz +3
The macroscopic phenomenon of filtration is the separation between suspended and liquid phases and it takes place in natural environments (e.g. groundwater, soil, hyporheic zone) a…
Tidal fluctuations and spatial heterogeneity lead to trapping and chaotic mixing in coastal aquifers
Satoshi Tajima, Marco Dentz
The combined effect of tidal forcing and aquifer heterogeneity leads to intricate transport patterns in coastal aquifers that impact both on solute residence times and mixing dynam…
Turbulent Pipe Flow of Thixotropic Fluids
Noman Yousuf, Daniel Lester, Murray Rudman +2
Complex materials with internal microstructure such as suspensions and emulsions exhibit time-dependent rheology characterized by viscoelasticity and thixotropy. In many large-scal…
Is Chaotic Advection Inherent to Heterogeneous Darcy Flow?
Daniel R. Lester, Michael G. Trefry, Guy Metcalfe +1
At all scales, porous materials stir interstitial fluids as they are advected, leading to complex distributions of matter and energy. Of particular interest is whether porous media…
